| − | I used to find the prime factors of the remaining distance until the next turn. It starts off difficult (for me) at 99 miles, etc. When it gets down to 30 miles, it gets easier. Then, at 9.9 miles, I have a tenth the time to factor 99 again, and it gets easier as the numbers get smaller. This is actually a pretty good way to pass the time while driving. {{unsigned ip|108.162.219.202}} | + | I used to find the prime factors of the remaining distance until the next turn.

| − | Paying attention to your driving might be a benefit. To yourself and others. Just sayin'.[[User:Jakee308|Jakee308]] ([[User talk:Jakee308|talk]]) 20:00, 24 April 2015 (UTC)

| − | I wonder how much time Randall spent trying to find a time that is not prime but the time + 1200 would be. {{unsigned|Flewk}}

| − | :Took me about 5 minutes with a script after getting a list of primes from the internet: 1:19; 1:21; 2:09; 2:47; 2:53; 2:59; 3:23; 3:43; 4:07; 4:13; 4:27; 4:37; 5:33; 5:53; 5:59; 6:11; 6:23; 7:07; 7:13; 7:31; 7:49; 8:03; 8:17; 9:13; 9:31; 9:43; 10:03; 10:07; 10:37; 10:43; 11:11; 11:33; 11:39; 11:41; 11:47; 11:57 (also the technical cases of: 12:03; 12:05; 12:07; 12:11; 12:19; 12:41; 12:43; 12:47; 12:53) . --[[Special:Contributions/173.245.52.27|173.245.52.27]] 06:18, 20 January 2016 (UTC)

| − | You know, in the state of Massachusetts, which is where Randall said he lives in the book ''What If?'', mile markers on the highway are placed every '''''0.2 miles''''', so he would get only twelve seconds per marker if he's trying to do each and every one (less if he's slightly speeding like everyone else does when there's no traffic).

| − | I added another explanation for the title text. It seems to me that factoring the (often same) mile marker numbers is a bit boring. [[User:Lanmi|Lanmi]] ([[User talk:Lanmi|talk]]) 11:55, 23 April 2016 (UTC) Lanmi

| − | Why would factoring become secondary problem after switching to km?
